PROBLEM TO BE SOLVED: To prevent the wasteful consumption of developer caused by the drying of isoper on an image carrier. SOLUTION: As soon as the trailing edge of a latent image on a photoreceptor 1 in a final copying stage, which is formed by a latent image forming device 20, passes through the developing roller 31 of a developing device 30 for developing the latent image to be a toner image, the supply of the developer to the device 30 is stopped. As soon as the trailing edge of residual toner on the photoreceptor 1 after transferring the toner image to transfer paper passes through the cleaning blade 52 of a cleaning device 50 for removing the residual toner, the blade 52 and a cleaning roller 51 are separated from the photoreceptor 1. |
